To all/whom if NHIII/ (ff/IH'UIR.

Be it known that 1, Almost. Wnoxnsne, a citizen of the United States, residing at .iJUS Angeles, in the county of Los Angelcs and State of California, have invented a new and useful Permanent Binder l'or Loose-Leaf .liccords, of which the following is a specification.

The main object of this invention is to fit cilitatc the insertion of leaves in loose-leaf binders.

Another object of the invention is to provide means for permanentiy locking records in the binder.

The accompanying drawings illustrate the invention, and, referring to the same, Figure 1 is a perspective of the binder in position for insertion of leaves. Fig. 2 a section of the back or fastening portion of the binder in open position. big. .13 a transverse section thereof in closed position. Fig. 4 is an edge View of part of the locking-bar. Figs. .5, e, and 7 are side views thln'co'i' in unlocked, telnporarily-loclied, and permanentlylockcd positions. Fig. 5 shows a n'iodii'icd form of the back device.

1 designates the back nil-lube! or plate,

preferably formed of sheet metal bent. into channel shape and having the boolvback 2 hrmly scoured thereto, as by means of screws or rivets 3 3 passing through. the upturned walls 4.- L of member l and into book-back.

6 6' designate the cove'r members of the book.

A strip or bar 7 is hinged at S directly to the top edge of wall *1. and carries the pins, studs, or standards 9 to engage and hold the paper, which is suitably perforated to slip over said pins. Said bar 7 can be turned up to bring the pins El into upright position, so as to facilitate the/insertion of sheets, and can then be turned down to extend thcpius across. the channeled back member 1. At the other side of this channeled back member is u locking device for the pins,consisting of a bar LU, sliclably mounted in a. case or guide 11, formed on the side wall 4. This case may be formed by an angle-strip 11, his tened to wall 4 by rivc'ts 3, so as to leave between said strip and wall a space for reception and "nidance of the lockin bar 10.

a a C (Jase 11 has notches l1 for passage of pins J. Locking-bar 10 has a lug or bend 10 at the end to enable it to -be grasped in moving it in its "guide and is prov (led with pcrfm'ations 12 for passage of rivets 3 imd with notches 13 for reception of pins 9, said notches 13 having rearward extensions 1 3, into which the pins enter when the bar 10 is pushed. in, the arms or projections 14.- above said extension serving to hold down or lock the pins. Pins't) have notches oi slits l5 engaged by said lugs to more firmly bind the parts together.

It is usual to bend in the joint or flexible portion between the back and cover, with the result that when the binder is opened the inner corners of the cover will form ridges, preventing the leaves from lying llat. To overcome this, I. prefer to attach the rigid cover members (3 and (5 to the outer ply jll) of the cover at a little distance from the back of the book. so that the inner corners 6 of the cover members are spaced outwardly from and sag to nearly a level with the bent portions of inner ply 22 when the book is open, so that there will be no bending of the sheets 23. 24 designates lnacing-hais' glued or otherwise secured between the case 1] and the side 21 of the back 11.

The above-described binderconstitutes a binder which is complete in itself: For some purposes i. prefer to use in connection there with means for permanently loeltin the-bar in. inner or locking position. Sue 1 means may consist ol' a detent 17, formed, for example, as a leaf-spring on bar 10, which in the normal locking movement of bar 10 slides idly in the case 11 over the top of a pin or lug is, but which when the bar is pressed in farthcr engages back of said pin 18 to hold the bar lrom being again pulled out. A mov able or removable stop is provided for normally limiting this inward movement, so that this permanent locking el'lect cannot .take place. This stop may consist of a screw 19. screwing into the slide-bar 10 and engaging the end of case 1] to limit the movelncnt'oi' bar 10. ()n removing the screw the next inward movement of bar 1U will cause engagement of s iring-detent 17 with )in 1b, and the binder wi l be permanently l'OCiiQtl by the .automatic action of said detent 17.

The construction. may be variously modiiied without departing from the invention. Fig. 8 shows a form of the invention in which the pins 9 instead of being straight, as in F ig. 1, are curved. i i a In practical use the leaf-holding means 9 may be readily swung up out of the channeled member For the reception or. removal of the leaves,and when returned to normal position said lead-holding means are olnunbered in the channeled back ]H(,Il1l)Ul',W'l\l0ll gives permanent form to the back of the book. The under surl'aee 2U ol' the cover is fastened to the (-over members (3 ii and forms flexible means eonnecting said cover members with the edges ol" the baek member, as clearly shown in Figs. 12,3,and b, above the level of the leafholding means when the bookis laid open.

Ielaiml In a loose-leaf himler, a channeled back member and a bar hinged thereto carrying leaf-engaging pins, and adapted to lold into the channel of the bark member.

2. In a loose-leaf binder, a channeled back member, abar hinged lhereto carrying leafengaging pins and arranged to fold into the ehannel ol" the back member, and a locking means'ior engaging said pins, when the same are in the ehannel.

3. In a loose-leaf binder, a channeled back member, a looking-bar at one side thereof, a bar adapted to fold into the channel of the hack member hinged to the other side of said member and carrying leaf-engaging pins standing upright in one position oi the bar to receive the leaves, and am'oss the channeled member in another position ol" the bar, to engage the locking-bar.

4. hi it loose-leaf binder, a leaf-engaging member, a loeking member therefor, an automatieally-operating looking-detent for the locking member preventing its backward movement when engaged therewith, and means normally preventing the engagement of said lUUlx'llIQ-(lOi-Ullt.

5. ln :1 loose-leaf binder, a leaf-engaging member, a locking member therefor, means for normally limitin the movement of the looking member am a detent engaging the locking member, when it exceeds the normal movement, to prevent return movement.

6. In a loose-leaf binder, a leaf-engaging member, a locking member therefor having a definite normal movement, and a detent enaging the locking member when it exceeds the normal movement, to lock said bar.

7. In a loose-leaf binder, a leaflengaging member, a locking member therefor, movable means for normally limiting the movement of the locking member, and a detent engaging the locking member when it exceeds the normal movement, to prevent return movement.

8'. In. a loose-leaf binder, a leafengaging member, a locking member therefor, removr able means for normally limiting the movement of the locking member, and a detent engaging the locking member when it exceeds the normal movement, to prevent return movement.

1). A locking device for loose-leaf binders comprising a case member, a locking member 'slidable thereon, one of said members being provided with a projection and the other with a spring-detent to engage such projection in a certain relative position of the members, and a removable stop to revent the relative movement of said. mem )ers to said position.

In testimony whereof I have hereunto set my hand, at .Los Angeles,(lalil"ornia, this 9th day of M'ay, 1905.
